Spieth is a round away from $10 million bonus

Jordan Spieth was so consumed with trying to make birdies and save pars on a rugged, rainy afternoon at the Tour Championship in Atlanta that he didn't realize until after he signed for a 2-under 68 that he had a one-shot lead.

He knows exactly what's at stake Sunday in what is shaping up as a dynamic end to the season.

Spieth made four big par saves and ended with a 20-foot birdie to overtake Henrik Stenson for the lead at East Lake. Already with the best year in golf, the Masters and U.S. Open champion is now one round away from the richest year in golf history.

A victory would push him over a record $12 million for the season, and give him the $10 million bonus for winning the FedEx Cup.

"No matter what, it's a dream-come-true season," said Spieth, who was at 8-under 202. "So I don't need tomorrow to justify it. I'm not going to sit here and say $10 million doesn't mean anything to me, because it does. It's a fantastic bonus.

"I'll work hard for the win tomorrow because I want to win this golf tournament. It would be special to get your name on that trophy."

Set the record: Sebastian Giovinco, who broke the MLS single-season points record, assisting on two Toronto goals to push his total to 35. Chris Wondolowski had 34 with San Jose in 2012.

Suffered an injury: Lionel Messi, who tore a ligament in his left knee during a Spanish league match. He is expected to be out two months and miss two of Argentina's World Cup qualifiers .

Encouraged by running back Eddie Lacy and receiver Davante Adams' progress in recoveries from ankle injuries, the Green Bay Packers could be without veteran safety Morgan Burnett after he reinjured his troublesome calf early in practice Friday.

The Packers listed Lacy, Adams and Burnett as questionable Saturday on the injury report for their home game Monday night against Kansas City. Coach Mike McCarthy sounded much more hopeful about Lacy and Adams than he did about Burnett. McCarthy said Burnett could not have practiced Saturday had practice been scheduled.

The Seattle Seahawks activated star safety Kam Chancellor and waived safety Dion Bailey. Chancellor had held out until Wednesday, seeking a new contract. Coach Pete Caroll said Chancellor would play Sunday against the Bears.
